Dengue Incidence Soars in Asia:
The Fever Is Urban, It Travels

Dengue fever, the potentially fatal mosquito-born virus, is spreading faster in Asia than anywhere else in the world. And being inside a plane at 10,000 meters is no protection.

A week after flying from Bangkok to Vientiane, Carol Cassidy, her husband, her son and three other passengers came down with severe cases of dengue. The plane was their only link. (A week is the average incubation period for dengue.)
